The slaying of Botham Jean by Dallas police Officer Amber Guyger, killings of police officers in Dallas and Richardson, and a 25-year-old man who posed as a high schooler all dominated headlines in 2018.

Here's a look back at some of the high-profile police news in the Dallas area this past year, including updates on where the cases stand now.

Italy school shooting

A 16-year-old was taken into custody in January after he opened fire in the Italy High School cafeteria Jan. 22, wounding 15-year-old Noelle "Cricket" Jones. Ellis County prosecutors will try the suspect, Chad Anthony Padilla, as an adult.

"It's the hardest day we've ever had," Police Chief Jimmy Spivey said the morning after Sherrard's death. "Officer Sherrard is a brave, tenured police officer who died in the service to his community."

Officer Rogelio Santander, 27, died a day after a routine shoplifting call at a Lake Highlands Home Depot ended in bloodshed.

A small memorial formed on the front step of 5913 Mimosa Lane in Rowlett on May 7. Policarpo Gonzalez-Flores, 40, shot his 11-year-old son, James Gonzalez, before killing himself on May 5, according to authorities.

Hillcrest High School impostor

Sidney Bouvier Gilstrap-Portley, 26, was first jailed on charges of tampering with a government record in May for enrolling at the school under a fake identity. He was later charged with indecency with a child after a girl told police she had been in a relationship with Gilstrap-Portley when she was 14.

Gilstrap-Portley was indicted on the indecency charge in December. The mother of the girl he dated has said she plans to sue the district.
